Heat waves will become more and more common in the UK because of climate change, and this is threatening many British landscapes. For instance, protected wildflower meadows in the UK are expected to experience a reduction in biodiversity, as many characteristic hay meadow wildflowers have lower temperature tolerance than dominant grasses. Unfortunately, the effects of rising temperature are understudied in hay meadows and other systems with dense foliage. One of the challenges in predicting the impact of rising temperatures on dense natural environments is that dense plant communities form microclimates which are important buffers to extreme temperatures.
This research will investigate the extent to which native meadow species form microclimates and how this influences resilience to heat waves. This work will involve growing various meadow species at different densities in the lab and observing the microclimate formation, local humidity, thermal tolerance and acclimation, and phenotypes under different growth-chamber simulated heat waves. You will have the opportunity to learn how to develop mathematical models to explain the observations and make predictions about various climate change scenarios. The long-term aim is to be able to predict how spatial organisation of plant communities will influence the formation of microclimates, and then evaluate how this influences their temperature tolerance under climate change. This will be especially important research to conduct in agriculturally-managed landscapes such as hay meadows, as farmers may be able to adapt the species composition and planting densities to improve the thermal tolerance of the ecosystem.
